Metal mesh is helpful in relation to two complications of total hip replacement; namely, migration of the trochanter and fatigue fracture of the medial wall of the acetabulum. Mesh is applied over the greater trochanter in instances when the trochanter is excessively porotic and would crush as the wires are tightened. It is used to "recapture" the trochanter or trochanteric fragments if migration has occurred. The wires are then brought through the mesh and tied over the mesh, thus distributing the load widely across the porotic trochanter. The problem of a thin medial acetabular wall is dealt with by medially embedding a hemisphere of metal mesh in the methacrylate creating the effect of reinforced concrete. This increases the physical properties of the methacrylate and helps to distribute the load to the public, ischial and iliac portions of the socket. Potentially this approach will be useful in treating fatigue fractures of the medial acetabular wall after total hip replacement. Thirteen patients treated using chrome cobalt metal mesh in association with total hip replacement are presented.
金属网对于全髋关节置换的两种并发症有帮助；即转子迁移和髋臼内壁疲劳骨折。当转子骨质过度疏松且在拧紧钢丝时会被压碎的情况下，可将金属网覆盖在大转子上。如果已经发生迁移，可使用金属网“固定”转子或转子碎片。然后将钢丝穿过金属网并系在金属网上，从而将负荷广泛分布在骨质疏松的转子上。髋臼内侧壁薄的问题可通过在甲基丙烯酸酯中内侧嵌入半球形金属网来解决，这会产生钢筋混凝土的效果。这增加了甲基丙烯酸酯的物理性能，并有助于将负荷分布到髋臼窝的耻骨、坐骨和髂骨部分。这种方法可能对治疗全髋关节置换术后髋臼内侧壁的疲劳骨折有用。本文介绍了13例使用铬钴金属网结合全髋关节置换治疗的患者。
